Can you do this to any other metal?

Superelasticity

Superelasticity

Superelasticity is the ability of Nickel-Titanium alloys of recovering large deformations up to 8% after unloading. For example, here we have a 3D object forming the superelasticity word. When presure applies on one side, while keeping the bottom as a fixed support, the object gets a large and temporary deformation. No problem at all as the material is working inside the elastic zone. Once pressure ends, these 3D letters get back to their initial shape, finishing the superelastic cycle.

Unlike shape memory letters, which maintain deformation after unloading (waiting for some heat to release the memory effect), these recover the shape after load finishes, without the need for a heat source. Due to the higher percentage of Nickel in this superelastic alloy than in those shape memory letters, the transformation temperature value of the superelastic alloy is lower and therefore, at room temperature, usually this value is always reached and the alloy is in austenite state. Deformations occur at the austenite stage, causing what is called “induced martensite”.

Finally, we’d like to invite you to take a look at our Shop. We are selling this example as well as many other solved SMA files for Ansys Workbench 18.1 or higher. Also, if you have a particular project, don’t hesitate to Contact us. We’ll try to do our best to help you.

SMA Simulation Shop Opening

Welcome to SMA Simulation Shop. Today is the opening of our shop. We sell solved Finite Elements simulation files of Shape Memory Alloys, under Ansys Workbench 18.1 or above environment.

Here you will find solved files to check material and setup settings. SMA alloys have two main properties: shape memory effect and superelasticity. Ansys Workbench software simulates the complex thermo-mechanical behavior of this amazing metal.

After you buy a file and make the payment, you will get a download link. Files are compressed and you need to use the “restore archive” option inside Ansys Workbench. Files are for version 18.1 or higher. These files won’t work on lower versions and therefore we recommend you check out your software version first.

You will need to provide a 3D model in any known file format. If you cannot provide this, we can make this model.

Finally, we really hope you like our shop. Probably, we are the only ones that sells solved Shape Memory Alloys files on the internet. In addition, we offer simulation services. As a result, we are here to help you on your SMA project.

You can also visit our YouTube channel to find more videos on Shape Memory Alloys

Happy simulations!
